Here's what we have so far for the next WFG reissue release. It'll contain two eps and a live set from 81.

The front cover proportions will be adjusted and back cover will get a couple more inverted crosses at the bottom. There's actually another Spot UV Gloss layer that goes over this layout which includes a huge WFG logo that prints over the inside gatefold. Everything on the front cover will be spot UV-ed.

You could do a an inverted shaped wrapping were to place the record + jacket inside. Something close to what you did for the Sabbat boxet. Sure that it would be huge and damn expensive but I think that would fit great with the band and album's concept layout.
